In this embodiment, the two dial units 2 are a downshift dial unit 2 and an upshift dial unit 2, respectively, and in order to facilitate the adjustment of the rotation angle of the two dial units 2 (that is, the adjustment of the rotation angle by operating the switch mounting base 21), the first pivot member 23 is elastically arranged; specifically, the switch mounting base 21 can be operated to rotate and adjust around the first pivot member 23 at one end only after the first pivot member 23 is loosened, so that the key 22 on the switch mounting base 21 is more convenient for a user to dial and finger, and meanwhile, the key 22 adopts a mode of elastically pressing the end part, so that the switch mounting base is more convenient to use and has the advantages of simple structure and convenience in adjustment.

In one embodiment, each switch mounting base 21 is provided with a positioning member 24, and is positioned by the positioning member 24 in cooperation with the dialer body 1 when the switch mounting base 21 is rotatably adjusted about the first pivot member 23.

In this embodiment, the first pivot member 23 is loosened, the switch mounting base 21 is operated to rotate and adjust around the first pivot member 23 at one end, and the positioning member 24 is matched to assist the switch mounting base 21 to rotate and position to a required position, and the first pivot member 23 is fastened after rotating to a required angle, so that the rotation and adjustment can be completed; has the advantages of accurate adjustment and positioning.

Referring to fig. 3 and 4, in one embodiment, the finger-dialer base 1 is provided with two mounting locations 11, each mounting location 11 is provided with a mounting hole 111, and the first pivot member 23 penetrates through one end of the switch mounting base 21 and the positioning member 24 and is screwed in the corresponding mounting hole 111; when the first pivot member 23 is screwed to the corresponding mounting hole 111, the switch mounting base 21 can be matched and fixed with the corresponding mounting position 11 through the positioning member 24; when the first pivot member 23 is screwed loose in the corresponding mounting hole 111, the switch mounting base 21 is rotatably adjusted and positioned in cooperation with the corresponding mounting position 11 by the positioning member 24.

In this embodiment, the mounting hole 111 may be a threaded hole, and the first pivot member 23 may be a half-thread screw, where the thread on the half-thread screw is located at the end tail of the half-thread screw; based on the above, the end tail of the first pivot member 23 penetrates through one end of the switch mounting base 21 and the positioning member 24 and is then screwed into the mounting hole 111, so that the threaded connection can be realized, the switch mounting base 21 and the positioning member 24 can be abutted against the mounting position 11 by operating the first pivot member 23 to be screwed into the mounting hole 111, and the switch mounting base 21 can be prevented from being loosened by the positioning member 24 to be matched with the mounting position 11; the angle of the switch mounting base 21 can be rotationally adjusted by operating the first pivot member 23 to rotate out of the mounting hole 111 to loosen the switch mounting base 21 and the positioning member 24 relative to the mounting position 11.

Specifically, the mounting position 11 is provided with a plurality of positioning notches 112, and the plurality of positioning notches 112 are distributed on the circumferential outer side of the mounting hole 111 in a circular ring direction; the side of the positioning piece 24 contacted with the installation position 11 is provided with a plurality of positioning bulges 241; the plurality of positioning recesses 112 are in one-to-one correspondence with the plurality of positioning projections 241. Based on this, when the first pivot member 23 is fastened, the switch mounting base 21 is positioned by the positioning member 24 being fitted to the mounting position 11, the plurality of positioning projections 241 of the positioning member 24 are in one-to-one correspondence in the plurality of positioning recesses 112 of the mounting position 11, so that the switch mounting base 21 can be prevented from being loosened; when the first pivot element 23 is loosened, the switch mounting base 21 can be rotationally adjusted and drives the positioning element 24 to synchronously rotate, and in the process of rotational adjustment, the positioning protrusion 241 on the positioning element 24 rotates relative to the positioning notch 112 of the mounting position 11, so that an adjustment feedback sense is generated, and a user can conveniently sense the angle of rotational adjustment; it should be appreciated that because the positioning notches 112 and the positioning protrusions 241 are all distributed in a circular ring shape, the number of positioning notches 112 and positioning protrusions 241 may be set to define the angle of each rotational adjustment.

More specifically, when the switch mounting base 21 is rotationally adjusted relative to the dialer base 1 about the axis of the first pivot member 23, the positioning member 24 needs to be driven to rotate synchronously, so that an adjustment feedback sense can be generated; based on this, a limiting opening 211 may be provided at the bottom of one end of the switch mounting base 21, and when the first pivot member 23 is in a fastening state or in a loose state, one side of the positioning member 24 facing away from the mounting position 11 is always embedded in the limiting opening 211, so as to limit the positioning member 24 to rotate relative to the limiting opening 211 in the axial direction of the first pivot member 23, so that the positioning member 24 can be driven to rotate synchronously when the switch mounting base 21 is rotationally adjusted.
